OIL-STOVE.

SPECIFICATIUN forming part of Letters Patent No. 670,301, dated March 19, 1901,

Application filed May 25, 1900. Serial No. 13,004. No model.

To all whom it nuty concern:

Be it known that I, LABS I-l. SOLOSTH, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification.

My invention relates to improvements in oil-stoves, and particularly to what is known as a blue-flame oil-stove, in which annular wicks are used; and its objects are, first, to provide an oil-stove having an annular wick actuated by a perforated tube and serrated wheels and idlers in such a manner that the tube cannot bind in its bearings and which will avoid all danger of friction; second, to provide an oil-stove having a tube or thimble inside of the wick which conveniently slips over the inner tube and leaves sufficient space between the wick and the said tube to prevent all danger of friction when raising and lowering the wick and having a head or projection at the lower end, so as to securely hold the wick to proper place and also to prevent impurities in the oil from working up through the wick and coming in contact with the flame and avoiding all danger of an impure light or an un-uniform flame; third, to provide two or more idlers to guide the perforated wick-tube when being raised and lowered by a serrated wheel or wheels; fourth, to provide an oil-stove having a suitable and convenient means of filling the oil-tank in a blueflame oil-stove, and, fifth, to provide an oilstove having a burner consisting of but two piecesthe burner proper and a spreader, which is attached to the top of the burner by means of a screw. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 isa vertical section on the line X X of Fig. 2, showing the frame and body of my oil-stove partly in section. Fig. 2 is a sectional plan of the stove on line y y of Figs. 1 and 4:, showing the manner in which to 0perate the wick in connection with the perforated tube. Fig. 3 is a detail side view with parts broken away to show the perforated tube in connection with the serrated Wheels and the plain-faced idlers. Fig. 4 is a central vertical section of same, shown on line .2 of Fig. 6. Fig. 5 is a detail side view with parts broken away to show the perforated tube in connection with the serrated wheels and idlers. Fig. 6 is a top plan of the stove with the top or spreader removed. Fig. 7 is a top plan of my burner with the top or spreader removed. Fig. 8 is a side view of my burner complete. Fig. 9 is a vertical seo tional view showing the appliance for filling the oil-tank.

Similar letters referto similarparts throughout the several views.

Arepresents the frame or cabinet of my stove. B shows the top of same.

0 is the body of the stove.

D is the outer tube, which receives the oil from the small tube a.

E is an oil-tank, which has a small tube a, through which the oil passes into the outer tube D.

F is the spreader on the top of the burner.

G is a metal ring which looks in or rests upon the flange or support I.

H is a piece of sheet metal which rests between the metal ring G and flange I and is perforated to regulate the passage of air to the burner.

I is a metal flange to support the top of the stove, and it is made to lock the same to the outer tube D with the screw-head at 6, so as to securely hold the two parts together and at the same time to conveniently be removed, as shown at e and e in Fig. 6.

J is a tube attached to the flange or support I to act as a guard for the top end of the wick, as shown in Fig. 4:.

K, K, and K" represent the burner, which is cast in one solid piece of metal.

At L in Fig. 4 the tube J is made larger, so that it will conveniently slip over the top of the wick.

m represents a short thimble designed to be inserted within the lower end of the wick 9 after it has been placed in the tube f and before placing it in the stove. The lower end of this thimble flares out and is provided with a bead M, which should be sufliciently prominent to press the wick closely against the inner surface of the tube f, so as to avert the danger of any impurities that may be in the oil or lower part of the stove from passing into and being carried through the wick to the flame at the upper end.

dis a small tube connected with the oiltank E and the tube D to carry the oil from the tank to the wick, as shown in Fig. l.

b is a thumb-wheel attached to the rod 19',

which operates inside of the sleeve j and connects with the serrated wheels j, which, together with the idlers i or 7 are regulated so as to uniformly raise and lower the wick by simply turning the thumb-wheel b.

b is a nut having a suitable packing between the joint, and when the same is screwed up tight it averts all danger of oil leaking through the sleeve j.

c is a cap to cover the opening of the oiltank E, whereby the same is filled.

d is a screw which fastens the spreader to the burner.

e is a screw to hold the tube J and flange I to its proper place.

e represents apertures in the flange I to receive the head of the screw 6.

6 represents lugs to securely hold the screw 6 to place.

f is a perforated tube, which, together with the wick, is raised and lowered by means of the serrated wheelsj and idlers 'L' and t.

g is an ordinary round or annular wick now in common use in connection with oil-stoves.

h is the inner tube, which forms a wall, so as to hold the oil between said tube and the outer tube D.

Z represents idlers regulated so as to mesh in the perforations of the tube f and operate in connection with the serrated wheels j for raising and lowering the wick.

t represents plain-faced idlers to operate in connection with the serrated wheels j for raising and lowering the wick.

j represents serrated wheels for operating the wick.

7c represents projections on the outer surface of the burner, which forms air-chambers between the burner and the inner tube It.

Z is a piece of sheet metal having perforations of a proper size, through which the air passes from the bottom of the stove to help regulate the light or flame.

m is a tube or thimble which rests inside of the wick and securely holds the wick to proper place.

N is a tube attached to the top of the stove and extending down inside near the bottom of the oil-tank, said tube having perforations at the lower end extending up to near the top of the said oil-tank for the oil to pass inside of said tube. At the top the said tube is made larger, so as to act as a funnel when filling the said oil-tank.

O is a cork attached to the rod Q and made to loosely fit inside of the tube N and will raise with the oil and act as a gage when filling the said oil-tank.

P is a catch to hold. the rod Q and cover R securely to place.

R is a cover to close up the top of the tube N, so as to avoid the danger of any dust or dirt getting into the tube N and working down into the oil-tank.

One of the principal features of my stove is the three serrated wheels which mesh in the perforated tube to raise and lower the wick. By having the three serrated wheels located in proper position it makes a true and perfect wick adjustment, which carries the wick up perfectly even and makes a perfect, even, and uniform light. This is one feature in particular that has never been accomplished by the old style of wick adjustments. This wick adjustment consists of three or more serrated wheels which can be used with equal facility on all oil stoves and lamps having a round or annular Wick orin fact on any heating or lighting apparatus where round or annular wicks are used. I do not restrict myself entirely to the several serrated wheels, as I show in Fig. 3 a modified form where I use one or more serrated wheels in connection with two or more plain-faced idlers which will also answer the purpose for raising, lowering, and guiding the wick-tube. In reference to the tube N, which is used for filling the oil'tank, I do not restrict myself entirely to filling of the oil-tank by means of said tube, as I find at c in Fig. 1 is also a very convenient place whereby to fill the said oil-tank. The action of the serrated wheels 2' diifers from that of the plain idlers in that with the serrated wheels the projecting points of the serrations enter the small apertures in the perforated tube, and thus in a degree guide the tube when being raised and lowered by the wheel j, while the plain idlers simply press upon the surface of the tube and do not guide it as perfectly as the serrated idlers or wheels do.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In an oil-stove, an annular wick and perforated adj usting-tube, in combination with serrated actuating-wheels,a shaft and thumbpiece connected with said wheels, and idlers acting upon the opposite side of the tube in unison with said actuating-wheels, substantially as and for the purpose set forth.

2. In an oil-stove, an annular wick and perforated adj 'ustingtube, serrated elevatorwheels and idlers, a thimble within the lower end of the wick, and an outwardly-projecting bead on said thimble, substantially as and for the purpose set forth.

3. In an oil-stove, an outer and an inner wick-tube, an annular wick, a perforated adjustingtube, serrated adj ustingwheels, idlers, a wick-guard having the lower end considerably flared and a flange upon said guard having elongated apertures, with one end large, lugs on the outer tube, and screws pass ing through said apertures and into said lugs, substantially as and for the purpose set forth.
